cache-test

[mk228]

I write a new cache policy. I want to test it and run 10 times. how can generate new traffic for each test?? each time i run my scenario , the results always show the same interest .

Hi,

are you using ndnSIM? can you share the code that you are running?

Hi, I use ndnSIM 2.0 . this code not use new policy. the code use LRU cache policy. But has problem that said.

include "ns3/core-module.h"

include "ns3/network-module.h"

include "ns3/ndnSIM-module.h"

namespace ns3 {

int main(int argc, char* argv[]) { CommandLine cmd; cmd.Parse(argc, argv);

//read topology from text AnnotatedTopologyReader topologyReader("", 25); topologyReader.SetFileName("src/ndnSIM/examples/topologies/cs.txt"); topologyReader.Read();

Ptr consumer[2]= {Names::Find("Src1"),Names::Find("Src2")}; Ptr router[3]= {Names::Find("Rtr1"),Names::Find("Rtr2"),Names::Find("Rtr3")};

Ptr producer = Names::Find("Dst1");

// Install NDN stack on all nodes ndn::StackHelper ndnHelperC;

ndn::StackHelper ndnHelperR;

ndn::StackHelper ndnHelperP;

for(int i=0;i<2;i++){ ndnHelperC.SetOldContentStore("ns3::ndn::cs::Nocache"); ndnHelperC.Install(consumer[i]);}

ndnHelperR.SetOldContentStore("ns3::ndn::cs::Lru", "MaxSize", "3"); // default ContentStore parameters ndnHelperR.Install(router[i]); }

return 0; }

Hi,

your code looks fine to me.

Since it is not a problem with our new policy I think you should post the question to the ndnSIM mailing list: ndnSIM@lists.cs.ucla.edu
